International Classification:

H04J 3/24

US Classification:

370473000

Abstract:

A method, “transparent switching”, is disclosed that enables the transfer of packet and TDM information flows on circuits between ports on interfaces to a network. These circuits consist of fixed-length transparent switching frames that occur at a provisioned fixed repetition rate. In the network interfaces, arriving flows from outside the network are groomed and mapped into circuits, using mapping procedures disclosed herein, that carry traffic to one or more destination network interfaces. Inside the network, circuits can be switched and multiplexed either on the basis of data containers, “transparent switching frames,” or on the basis of underlying transport technologies. The traffic flows that arrive at a destination interface from inside the network are removed from the transparent switching frames and delivered to the appropriate egress port. In networks that must carry a preponderance of packet traffic, transparent switching provides a simple means of providing delay and bandwidth guarantees to specific traffic flows. Transparent switching also provides for the establishment of signaling channels and for mechanisms for the rapid setup of circuits.

370 60

Abstract:

The present invention pertains to a packet switch. The packet switch is comprised of a global shared-memory queue having M storage addresses in which respective packets are stored, where M. gtoreq. 3 and is an integer. The packet switch is also comprised of a presentation network having N input ports for receiving packets and providing the respective packets to desired addresses in the queue, where N. gtoreq. 3 and is an integer. The queue is in communication with the presentation network for receiving the packets. The packet switch is also comprised of a distribution network having J input ports, where J. gtoreq. 1, for receiving packets from the queue and providing them to the desired output ports. The distribution network is in communication with the queue. There is also means for ordering packets received by the presentation network such that packets received sequentially by the presentation network are caused to be provided by the presentation network to consecutive addresses in the queue.

Abstract:

There is shown an apparatus for switching. The apparatus for switching comprises L switching modules which switch packets, where L. gtoreq. 2 and is an integer. In an embodiment, each of the L switching modules switch packets independent of any other switching module such that there is distributed switching of packets across the L switching modules. The apparatus also comprises an interconnection module which is connected to each of the L switching modules. The interconnection module that provides a passive backplane provides connectivity between the L switching modules. In an embodiment, the interconnection module provides space and time multiplexed connectivity between the L switching modules. In an other embodiment, the interconnection module is expandable without a priori knowledge of a final number of switching modules. In yet another embodiment, the interconnection module is reprogrammable in regard to connectivity between the L switching modules.
